Science KS1 / KS2: What materials are waterproof?
There are many types of materials, but only some are waterproof.
Join Dr Brain and his team of scientists as they test four everyday materials, looking at their properties to see if they are suitable to stop the leaking pipe.
The team will identify and test three different everyday materials: cotton wool, paper and plastic.
But which will have the properties needed to stop the leaking pipe?
This clip is from the series Ultimate Brain: Mad Lab.
Pupils could test a different selection of materials to see whether or not they were waterproof.
For each material they could make predictions based on the experiment they have seen.
These films are suitable for teaching Science at Key Stage 1 and 2 in England, Wales and Northern Ireland, and 1st and 2nd Level in Scotland.
